POTENTIAL HEALTH EFFECTS<br />
ACUTE HEALTH EFFECTS<br />
SWALLOWED<br />
! The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion.<br />
! The material has NOT been classified as "harmful by ingestion". This is because of the lack of corroborating animal or human evidence.<br />
The material may still be damaging to the health of the individual, following ingestion, especially where pre-existing organ (e.g. liver, kidney)<br />
damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality (death) rather than<br />
those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting<br />
however, unintentional ingestion is not thought to be cause for concern.<br />
! Ingestion of <strong>acid</strong>ic corrosives may produce burns around and in the mouth. the throat and esophagus. Immediate pain and difficulties in<br />
swallowing and speaking may also be evident. Swelling of the epiglottis may make it difficult to breathe which may result in suffocation. More<br />
severe exposure may result in vomiting blood and thick mucus, shock, abnormally low blood pressure, fluctuating pulse, shallow respiration<br />
and clammy skin, inflammation of stomach wall, and rupture of esophageal tissue. Untreated shock may eventually result in kidney failure.<br />
Severe cases may result in perforation of the stomach and abdominal cavity with consequent infection, rigidity and fever. There may be<br />
severe narrowing of the esophageal or pyloric sphincters; this may occur immediately or after a delay of weeks to years. There may be coma<br />
and convulsions, followed by death due to infection of the abdominal cavity, kidneys or lungs.<br />
! Ingestion of sulfamic <strong>acid</strong> may cause vomiting, diarrhoea and a drop in blood pressure. Asphyxia may occur from oedema of the glottis.<br />
After initial recovery, onset of fever indicates mediastinitis or peritonitis from perforation of the esophagus or stomach. Ingestion of greater<br />
than 10% solutions will cause lesions of the stomach.<br />
EYE<br />
! This material can cause eye irritation and damage in some persons.<br />
! The material can produce chemical burns to the eye following direct contact. Vapors or mists may be extremely irritating.<br />
! Direct eye contact with <strong>acid</strong> corrosives may produce pain, tears, sensitivity to light and burns. Mild burns of the epithelia generally recover<br />
rapidly and completely. Severe burns produce long-lasting and possibly irreversible damage. The appearance of the burn may not be<br />
apparent for several weeks after the initial contact. The cornea may ultimately become deeply opaque resulting in blindness.<br />
! If applied to the eyes, this material causes severe eye damage.<br />
SKIN<br />
! This material can cause inflammation of the skin oncontact in some persons.<br />
! The material can produce chemical burns following direct contactwith the skin.<br />
! Skin contact is not thought to have harmful health effects, however the material may still produce health damage following entry through<br />
wounds, lesions or abrasions.<br />
! Concentrated solutions may cause chemical burns. The effects of sulfamic <strong>acid</strong> on the skin appear to be limited to the effects of low pH.<br />
Concentrations of greater than 20% of sulfamic <strong>acid</strong> may injure the skin.<br />
Repeated application of a 4% solution of sulfamic <strong>acid</strong> several times a day for 5 days on the skin produced mild irritation.<br />
! Open cuts, abraded or irritated skin should not be exposed to this material.<br />
! Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine<br />
the skin prior to the use of the material and ensure that any external damage is suitably protected.<br />
! Skin contact with <strong>acid</strong>ic corrosives may result in pain and burns; these may be deep with distinct edges and may heal slowly with the<br />
formation of scar tissue.<br />
! Solution of material in moisture on the skin, or perspiration, may markedly increase skin corrosion and accelerate tissue destruction.<br />
INHALED<br />
! Inhalation of sulfamic <strong>acid</strong> may cause bloody spit, difficulty breathing, low blood pressure, headache, dizziness, bluish skin colour and lung<br />
congestion.<br />
! Persons with impaired respiratory function, airway diseases and conditions such as emphysema or chronic bronchitis, may incur further<br />
disability if excessive concentrations of particulate are inhaled.<br />
! Corrosive <strong>acid</strong>s can cause irritation of the respiratory tract, with coughing, choking and mucous membrane damage. There may be<br />
dizziness, headache, nausea and weakness. Swelling of the lungs can occur, either immediately or after a delay; symptoms of this include<br />
chest tightness, shortness of breath, frothy phlegm and cyanosis. Lack of oxygen can cause death hours after onset.<br />
! The material can cause respiratory irritation in some persons. The body's response to such irritation can cause further lung damage.<br />
CHRONIC HEALTH EFFECTS<br />
! Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or<br />
biochemical systems.<br />
Long term exposure to high dust concentrations may cause changes in lung function i.e. pneumoconiosis; caused by particles less than 0.5<br />
micron penetrating and remaining in the lung. Prime symptom is breathlessness; lung shadows show on X-ray.<br />
Repeated or prolonged exposure to <strong>acid</strong>s may result in the erosion of teeth, swelling and or ulceration of mouth lining. Irritation of airways to<br />
lung, with cough, and inflammation of lung tissue often occurs. Chronic exposure may inflame the skin or conjunctiva.<br />

Section 4 - FIRST AID MEASURES<br />
SWALLOWED<br />
!<br />
For advice, contact a Poisons Information Center or a doctor at once.<br />
Urgent hospital treatment is likely to be needed.<br />
If swallowed do NOT induce vomiting.<br />
If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent<br />
aspiration.<br />
Observe the patient carefully.<br />
Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconscious.<br />
Give water to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink.<br />
Transport to hospital or doctor without delay.<br />
EYE<br />
! If this product comes in contact with the eyes:<br />
Immediately hold eyelids apart and flush the eye continuously with running water.<br />
Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper<br />
and lower lids.<br />
Continue flushing until advised to stop by the Poisons Information Center or a doctor, or for at least 15 minutes.<br />
Transport to hospital or doctor without delay.<br />
Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.<br />
SKIN<br />
! If skin or hair contact occurs:<br />
Immediately flush body and clothes with large amounts of water, using safety shower if available.<br />
Quickly remove all contaminated clothing, including footwear.<br />
Wash skin and hair with running water. Continue flushing with water until advised to stop by the Poisons Information Center.<br />
Transport to hospital, or doctor.<br />
INHALED<br />
!<br />
If fumes or combustion products are inhaled remove from contaminated area.<br />
Lay patient down. Keep warm and rested.<br />
Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures.<br />
Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained.<br />
Perform CPR if necessary.<br />
Transport to hospital, or doctor.<br />
Inhalation of vapors or aerosols (mists, fumes) may cause lung edema. Corrosive substances may cause lung damage (e.g. lung edema,<br />
fluid in the lungs). As this reaction may be delayed up to 24 hours after exposure, affected individuals need complete rest (preferably in<br />
semi-recumbent posture) and must be kept under medical observation even if no symptoms are (yet) manifested. Before any such<br />
manifestation, the administration of a spray containing a dexamethasone derivative or beclomethasone derivative may be considered. This<br />
must definitely be left to a doctor or person authorized by him/her. (ICSC13719).<br />

NOTES TO PHYSICIAN<br />
! Treat symptomatically.<br />
For acute or short term repeated exposures to strong <strong>acid</strong>s:<br />
Airway problems may arise from laryngeal edema and inhalation exposure. Treat with 100% oxygen initially.<br />
Respiratory distress may require cricothyroidotomy if endotracheal intubation is contraindicated by excessive swelling<br />
Intravenous lines should be established immediately in all cases where there is evidence of circulatory compromise.<br />
Strong <strong>acid</strong>s produce a coagulation necrosis characterized by formation of a coagulum (eschar) as a result of the dessicating action of<br />
the <strong>acid</strong> on proteins in specific tissues.<br />
INGESTION:<br />
Immediate dilution (milk or water) within 30 minutes post ingestion is recommended.<br />
DO NOT attempt to neutralize the <strong>acid</strong> since exothermic reaction may extend the corrosive injury.<br />
Be careful to avoid further vomit since re-exposure of the mucosa to the <strong>acid</strong> is harmful. Limit fluids to one or two glasses in an adult.<br />
Charcoal has no place in <strong>acid</strong> management.<br />
Some authors suggest the use of lavage within 1 hour of ingestion.<br />
SKIN:<br />
Skin lesions require copious saline irrigation. Treat chemical burns as thermal burns with non-adherent gauze and wrapping.<br />
Deep second-degree burns may benefit from topical silver sulfadiazine.<br />
EYE:<br />
Eye injuries require retraction of the eyelids to ensure thorough irrigation of the conjuctival cul-de-sacs. Irrigation should last at least<br />
20-30 minutes. DO NOT use neutralizing agents or any other additives. Several liters of saline are required.<br />
Cycloplegic drops, (1% cyclopentolate for short-term use or 5% homatropine for longer term use) antibiotic drops, vasoconstrictive agents<br />
or artificial tears may be indicated dependent on the severity of the injury.<br />
Steroid eye drops should only be administered with the approval of a consulting ophthalmologist).<br />

FOOTNOTES<br />
1 PROTECTIVE ACTION ZONE is defined as the area in which people are at risk of harmful exposure. This zone assumes that random changes in wind direction confines the<br />
vapour plume to an area within 30 degrees on either side of the predominant wind direction, resulting in a crosswind protective action distance equal to the downwind protective<br />
action distance.<br />
2 PROTECTIVE ACTIONS should be initiated to the extent possible, beginning with those closest to the spill and working away from the site in the downwind direction. Within<br />
the protective action zone a level of vapour concentration may exist resulting in nearly all unprotected persons becoming incapacitated and unable to take protective action<br />
and/or incurring serious or irreversible health effects.<br />
3 INITIAL ISOLATION ZONE is determined as an area, including upwind of the incident, within which a high probability of localised wind reversal may expose nearly all persons<br />
without appropriate protection to life-threatening concentrations of the material.<br />
4 SMALL SPILLS involve a leaking package of 200 litres (55 US gallons) or less, such as a drum (jerrican or box with inner containers). Larger packages leaking less than 200<br />
litres and compressed gas leaking from a small cylinder are also considered "small spills". LARGE SPILLS involve many small leaking packages or a leaking package of greater<br />
than 200 litres, such as a cargo tank, portable tank or a "one-tonne" compressed gas cylinder.<br />

ACUTE EXPOSURE GUIDELINE LEVELS (AEGL) (in ppm)<br />
AEGL 1: The airborne concentration of a substance above which it is predicted<br />
that the general population, including susceptible individuals, could<br />
experience notable discomfort, irritation, or certain asymptomatic nonsensory<br />
effects. However, the effects are not disabling and are transient and<br />
reversible upon cessation of exposure.<br />
AEGL 2: The airborne concentration of a substance above which it is predicted<br />
that the general population, including susceptible individuals, could<br />
experience irreversible or other serious, long-lasting adverse health effects<br />
or an impaired ability to escape.<br />

MATERIAL DATA<br />
SULFAMIC ACID:<br />
! Sensory irritants are chemicals that produce temporary and undesirable side-effects on the eyes, nose or throat. Historically occupational<br />
exposure standards for these irritants have been based on observation of workers' responses to various airborne concentrations. Present<br />
day expectations require that nearly every individual should be protected against even minor sensory irritation and exposure standards are<br />
established using uncertainty factors or safety factors of 5 to 10 or more. On occasion animal no-observable-effect-levels (NOEL) are used to<br />
determine these limits where human results are unavailable. An additional approach, typically used by the TLV committee (USA) in<br />
determining respiratory standards for this group of chemicals, has been to assign ceiling values (TLV C) to rapidly acting irritants and to<br />
assign short-term exposure limits (TLV STELs) when the weight of evidence from irritation, bioaccumulation and other endpoints combine to<br />
warrant such a limit. In contrast the MAK Commission (Germany) uses a five-category system based on intensive odour, local irritation, and<br />
elimination half-life. However this system is being replaced to be consistent with the European Union (EU) Scientific Committee for<br />
Occupational Exposure Limits (SCOEL); this is more closely allied to that of the USA.<br />
OSHA (USA) concluded that exposure to sensory irritants can:<br />
cause inflammation<br />
cause increased susceptibility to other irritants and infectious agents<br />
lead to permanent injury or dysfunction<br />
permit greater absorption of hazardous substances and<br />
acclimate the worker to the irritant warning properties of these substances thus increasing the risk of overexposure.<br />
It is the goal of the ACGIH (and other Agencies) to recommend TLVs (or their equivalent) for all substances for which there is evidence of<br />
health effects at airborne concentrations encountered in the workplace.<br />
At this time no TLV has been established, even though this material may produce adverse health effects (as evidenced in animal experiments<br />
or clinical experience). Airborne concentrations must be maintained as low as is practically possible and occupational exposure must be kept<br />
to a minimum.<br />

PERSONAL PROTECTION<br />
Consult your EHS staff for recommendations<br />
EYE<br />
!<br />
Chemical goggles.<br />
Full face shield.<br />
Contact lenses pose a special hazard; soft lenses may absorb irritants and all lenses concentrate them.<br />
HANDS/FEET<br />
! Wear chemical protective gloves, eg. PVC.<br />
Wear safety footwear or safety gumboots, eg. Rubber.<br />
Suitability and durability of glove type is dependent on usage. Important factors in the selection of gloves include: such as:<br />
frequency and duration of contact,<br />
chemical resistance of glove material,<br />
glove thickness and<br />
dexterity<br />
Select gloves tested to a relevant standard (e.g. Europe EN 374, US F739).<br />
When prolonged or frequently repeated contact may occur, a glove with a protection class of 5 or higher (breakthrough time greater than<br />
240 minutes according to EN 374) is recommended.<br />
When only brief contact is expected, a glove with a protection class of 3 or higher (breakthrough time greater than 60 minutes according<br />
to EN 374) is recommended.<br />
Contaminated gloves should be replaced.<br />
Gloves must only be worn on clean hands. After using gloves, hands should be washed and dried thoroughly. Application of a non-perfumed<br />
moisturiser is recommended.<br />
OTHER<br />
!<br />
Overalls.<br />
PVC Apron.<br />
PVC protective suit may be required if exposure severe.<br />
Eyewash unit.<br />
Ensure there is ready access to a safety shower.<br />
!<br />
Respirators may be necessary when engineering and administrative controls do not adequately prevent exposures.<br />
The decision to use respiratory protection should be based on professional judgment that takes into account toxicity information,<br />
exposure measurement data, and frequency and likelihood of the worker's exposure - ensure users are not subject to high thermal loads<br />
which may result in heat stress or distress due to personal protective equipment (powered, positive flow, full face apparatus may be an<br />
option).<br />
Published occupational exposure limits, where they exist, will assist in determining the adequacy of the selected respiratory . These may<br />
be government mandated or vendor recommended.<br />
Certified respirators will be useful for protecting workers from inhalation of particulates when properly selected and fit tested as part of a<br />
complete respiratory protection program.<br />
Use approved positive flow mask if significant quantities of dust becomes airborne.<br />
Try to avoid creating dust conditions.<br />

The local concentration of material, quantity and conditions of use determine the type of personal protective equipment required.<br />
Use appropriate NIOSH-certified respirator based on informed professional judgement. In conditions where no reasonable estimate of<br />
exposure can be made, assume the exposure is in a concentration IDLH and use NIOSH-certified full face pressure demand SCBA with a<br />
minimum service life of 30 minutes, or a combination full facepiece pressure demand SAR with auxiliary self-contained air supply. Respirators<br />
provided only for escape from IDLH atmospheres shall be NIOSH-certified for escape from the atmosphere in which they will be used.<br />
ENGINEERING CONTROLS<br />
!<br />
Local exhaust ventilation is required where solids are handled as powders or crystals; even when particulates are relatively large, a<br />
certain proportion will be powdered by mutual friction.<br />
If in spite of local exhaust an adverse concentration of the substance in air could occur, respiratory protection should be considered.<br />
Such protection might consist of:<br />
(a): particle dust respirators, if necessary, combined with an absorption cartridge;<br />
(b): filter respirators with absorption cartridge or canister of the right type;<br />
(c): fresh-air hoods or masks<br />
Air contaminants generated in the workplace possess varying "escape" velocities which, in turn, determine the "capture velocities" of fresh<br />
circulating air required to effectively remove the contaminant.<br />
Type of Contaminant:<br />
direct spray, spray painting in shallow booths, drum filling, conveyer<br />
loading, crusher dusts, gas discharge (active generation into zone of<br />
rapid air motion)<br />
grinding, abrasive blasting, tumbling, high speed wheel generated<br />
dusts (released at high initial velocity into zone of very high rapid air<br />
motion).<br />

Simple theory shows that air velocity falls rapidly with distance away from the opening of a simple extraction pipe. Velocity generally<br />
decreases with the square of distance from the extraction point (in simple cases). Therefore the air speed at the extraction point should be<br />
adjusted, accordingly, after reference to distance from the contaminating source. The air velocity at the extraction fan, for example, should be<br />
a minimum of 4-10 m/s (800-2000 f/min) for extraction of crusher dusts generated 2 meters distant from the extraction point. Other<br />
mechanical considerations, producing performance deficits within the extraction apparatus, make it essential that theoretical air velocities are<br />
multiplied by factors of 10 or more when extraction systems are installed or used.<br />

isocyanates, metal nitrates/ nitrites, oxidisers, vinyl acetate, common metals and their alloys, water<br />
Contact with metals may result in the evolution of hydrogen (H2) which can form explosive mixtures in air.<br />
Inorganic <strong>acid</strong>s are generally soluble in water with the release of hydrogen ions. The resulting solutions have pH's of less than 7.0.<br />
Inorganic <strong>acid</strong>s neutralize chemical bases (for example: amines and inorganic hydroxides) to form salts.<br />
Neutralization can generate dangerously large amounts of heat in small spaces.<br />
The dissolution of inorganic <strong>acid</strong>s in water or the dilution of their concentrated solutions with additional water may generate significant<br />
heat.<br />
The addition of water to inorganic <strong>acid</strong>s often generates sufficient heat in the small region of mixing to cause some of the water to boil<br />
explosively. The resulting "bumping" can spatter the <strong>acid</strong>.<br />
Inorganic <strong>acid</strong>s react with active metals, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas.<br />
Inorganic <strong>acid</strong>s can initiate the polymerization of certain classes of organic compounds.<br />
Inorganic <strong>acid</strong>s react with cyanide compounds to release gaseous hydrogen cyanide.<br />
Inorganic <strong>acid</strong>s generate flammable and/or toxic gases in contact with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles,<br />
sulfides, and strong reducing agents. Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3),<br />
dithionites (SO2), and even carbonates.<br />
Acids often catalyze (increase the rate of) chemical reactions.<br />
Avoid strong <strong>acid</strong>s, bases.<br />

Section 11 - TOXICOLOGICAL INFORMATION<br />
TOXICITY AND IRRITATION<br />
! unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.<br />
TOXICITY<br />
Oral (rat) LD50: 3160 mg/kg<br />
IRRITATION<br />
Skin (human): 4 %/5 days (I)- Mild<br />
Skin (rabbit): 500 mg/24 h-SEVERE<br />
Eye (rabbit): 250 ug/24 h - SEVERE<br />
Eye (rabbit): 20 mg - Moderate<br />
! The material may produce severe irritation to the eye causing pronounced inflammation. Repeated or prolonged exposure to irritants may<br />
produce conjunctivitis.<br />
The material may cause severe skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the<br />
production of vesicles, scaling and thickening of the skin. Repeated exposures may produce severe ulceration.<br />
Asthma-like symptoms may continue for months or even years after exposure to the material ceases. This may be due to a non-allergenic<br />
condition known as reactive airways dysfunction syndrome (RADS) which can occur following exposure to high levels of highly irritating<br />
compound. Key criteria for the diagnosis of RADS include the absence of preceding respiratory disease, in a non-atopic individual, with<br />
abrupt onset of persistent asthma-like symptoms within minutes to hours of a documented exposure to the irritant. A reversible airflow<br />
pattern, on spirometry, with the presence of moderate to severe bronchial hyperreactivity on methacholine challenge testing and the lack of<br />
minimal lymphocytic inflammation, without eosinophilia, have also been included in the criteria for diagnosis of RADS. RADS (or asthma)<br />
following an irritating inhalation is an infrequent disorder with rates related to the concentration of and duration of exposure to the irritating<br />
substance. Industrial bronchitis, on the other hand, is a disorder that occurs as result of exposure due to high concentrations of irritating<br />
substance (often particulate in nature) and is completely reversible after exposure ceases. The disorder is characterised by dyspnea, cough<br />
and mucus production.<br />
Section 12 - ECOLOGICAL INFORMATION<br />
Refer to data for ingredients, which follows:<br />
SULFAMIC ACID:<br />
! Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment.<br />
! Do NOT allow product to come in contact with surface waters or to intertidal areas below the mean high water mark. Do not contaminate<br />
water when cleaning equipment or disposing of equipment wash-waters.<br />
Wastes resulting from use of the product must be disposed of on site or at approved waste sites.<br />
! Although inorganic chloride ions are not normally considered toxic they can exist in effluents at acutely toxic levels (chloride >3000 mg/l).<br />
the resulting salinity can exceed the tolerances of most freshwater organisms.<br />
Inorganic chlorine eventually finds its way into the aqueous compartment and as such is bioavailable. Incidental exposure to inorganic<br />
chloride may occur in occupational settings where chemicals management policies are improperly applied. The toxicity of chloride salts<br />
depends on the counter-ion (cation) present; that of chloride itself is unknown. Chloride toxicity has not been observed in humans except in<br />
the special case of impaired sodium chloride metabolism, e.g. in congestive heart failure . Healthy individuals can tolerate the intake of large<br />
quantities of chloride provided that there is a concomitant intake of fresh water.<br />
Although excessive intake of drinking-water containing sodium chloride at concentrations<br />
above 2.5 g/litre has been reported to produce hypertension, this effect is believed to be related to the sodium ion concentration.<br />
Chloride concentrations in excess of about 250 mg/litre can give rise to detectable taste in water, but the threshold depends upon the<br />
associated cations. Consumers can, however, become accustomed to concentrations in excess of 250 mg/litre. No health-based guideline<br />
value is proposed for chloride in drinking-water.<br />
In humans, 88% of chloride is extracellular and contributes to the osmotic activity of body fluids. The electrolyte balance in the body is<br />
maintained by adjusting total dietary intake and by excretion via the kidneys and gastrointestinal tract. Chloride is almost completely<br />
absorbed in normal individuals, mostly from the proximal half of the small intestine. Normal fluid loss amounts to about 1.5?2 liters/day,<br />
together with about 4 g of chloride per day. Most (90 - 95%) is excreted in the urine, with minor amounts in faeces (4- %) and sweat (2%)<br />
Chloride increases the electrical conductivity of water and thus increases its corrosivity. In metal pipes, chloride reacts with metal ions to form<br />
soluble salts thus increasing levels of metals in drinking-water. In lead pipes, a protective oxide layer is built up, but chloride enhances<br />
galvanic corrosion. It can also increase the rate of pitting corrosion of metal pipes.<br />
! Prevent, by any means available, spillage from entering drains or watercourses.<br />
! DO NOT discharge into sewer or waterways.<br />
